It seems to include characters such as '1' (0x31) and > '0' (0x30) which do not need to be escaped. It seems that the actual range > should be 0x00 - 0x1F and 0x7F+ as corroborated [by this > page|https://en.wikipedia.org/wiki/Unicode_control_characters]. > > This causes unnecessary escaping and regex substitutions on the CQLSH end > whenever common characters such as any punctuation or a 0 or a 1 appear in > the text column of a table. One might notice that a table with a text column > filled with 2's will take much less time to print than one with all 0's for > this reason. -- This message was sent by Atlassian Jira (v8.20.7#820007) --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
